结束了一个对象，我怎么这个工作吗？ [英] Ended up with an Object, how do I work with this?

问题描述

在<一个解决我的问题的一部分后， href=\"http://stackoverflow.com/questions/10092771/mvc-fundamentals-passing-work-along-to-the-view\">here,我意识到，我可以获取数据到视图，但后来我有另外一个问题。

（控制器）

  $这个 - ＆GT;负载＆GT;模型（'测试/ test_v_to_m_model'）;
$数据['MYDATA'] = $这个 - ＆GT; test_v_to_m_model-＆GT; display_character_info（）;
$这个 - ＆GT;负载＆gt;查看（'测试/ test_v_to_m_view'，$数据）;
 

（模型）

  $查询= $这个 - ＆GT; doctrine-＆GT;的EM＆GT;的createQuery（从ORM \\ Dynasties2 \\字符U选择U）;
返回$查询 - ＆GT;的getResult（）;
 

（视图）

 的foreach（$ MYDATA为$关键=＆GT; $行）{
   的print_r（$行）;
}
 

这将返回输出像这样：

  

ORM \\ Dynasties2 \\字符对象（[ID：ORM \\ Dynasties2 \\特点：私人] => 76名：ORM \\ Dynasties2 \\特点：私人] => Gwayn [whichFamily：ORM \\ Dynasties2 \\特点：私人] = > 12 [bornDate：ORM \\ Dynasties2 \\特点：私人] => -467 [deathDate：ORM \\ Dynasties2 \\特点：私人] => -6 [marriedTo：ORM \\ Dynasties2 \\特点：私人] => 77 marriedDate：ORM \\ Dynasties2 \\特点：私人] => -304 [婚姻code：ORM \\ Dynasties2 \\特点：私人] => [宗教：ORM \\ Dynasties2 \\特点：私人] => 0 isFemale：ORM \\ Dynasties2 \\字符：私人] => 0 betrothedTo：ORM \\ Dynasties2 \\特点：私人] => [fathersId：ORM \\ Dynasties2 \\特点：私人] => 0 successionOrder：ORM \\ Dynasties2 \\特点：私人] => 0为pregnant：ORM \\ Dynasties2 \\特点：私人] => [pregnantTurnsLeft：ORM \\ Dynasties2 \\特点：私人] => [marriedOutOfFamily：ORM \\ Dynasties2 \\特点：私人] => [bornMatrilineal：ORM \\ Dynasties2 \\性状：私人] =>）

所以...我只是不知道如何与这个 - 做任何事情，我想一个嵌套的foreach呼应数据并不能得到它的工作。我期望它，因为这是一个的对象的，不是的阵列的，是正确的？

1. 我究竟如何访问/操纵这些领域？




2. 有不同的code，我可以在我的Doctrine2 / codeIgniter2模型中使用，这将使数据更容易字段名称 - 像相当于SQL作为

解决方案

您应该能够指针访问对象，像这样：

 的foreach（$ MYDATA为$关键=＆GT; $行）{
   回波（$行向和SEQ ID）;
   回波（$行向＆GT;名）;
}
 

stdClass的是PHP的通用空类。下面是使用提供了很好的教程： http://krisjordan.com/dynamic-属性 - 在PHP与 - stdClass的

编辑：

尝试使用访问：

 回声（$行向＆GT;的getId（））;
 

After solving part of my problem over here, I realized that I could get the data into the view, but then I had another problem.

(controller)

$this->load->model('testing/test_v_to_m_model');
$data['mydata'] = $this->test_v_to_m_model->display_character_info();
$this->load->view('testing/test_v_to_m_view', $data);

(model)

$query = $this->doctrine->em->createQuery("select u from ORM\Dynasties2\Characters u");
return $query->getResult();

(view)

foreach ($mydata as $key => $row) {
   print_r($row);
}

This returns output like so:

ORM\Dynasties2\Characters Object ( [id:ORM\Dynasties2\Characters:private] => 76 [name:ORM\Dynasties2\Characters:private] => Gwayn [whichFamily:ORM\Dynasties2\Characters:private] => 12 [bornDate:ORM\Dynasties2\Characters:private] => -467 [deathDate:ORM\Dynasties2\Characters:private] => -6 [marriedTo:ORM\Dynasties2\Characters:private] => 77 [marriedDate:ORM\Dynasties2\Characters:private] => -304 [marriageCode:ORM\Dynasties2\Characters:private] => [religion:ORM\Dynasties2\Characters:private] => 0 [isFemale:ORM\Dynasties2\Characters:private] => 0 [betrothedTo:ORM\Dynasties2\Characters:private] => [fathersId:ORM\Dynasties2\Characters:private] => 0 [successionOrder:ORM\Dynasties2\Characters:private] => 0 [isPregnant:ORM\Dynasties2\Characters:private] => [pregnantTurnsLeft:ORM\Dynasties2\Characters:private] => [marriedOutOfFamily:ORM\Dynasties2\Characters:private] => [bornMatrilineal:ORM\Dynasties2\Characters:private] => )

And so... I just don't know how to do anything with this- I tried a nested foreach to echo data and couldn't get it to work. I expect that its because this is an Object, not an Array, is that correct?

1. How exactly can I access/manipulate these fields?

2. Is there different code that I can use in my Doctrine2/CodeIgniter2 model that will give the data easier field names - like the equivalent to sql AS?

解决方案

You should be able to access the object with pointers, like so:

foreach ($mydata as $key => $row) {
   echo($row->id);
   echo($row->name);
}

stdClass is php's generic empty class. Here is a nice tutorial on using this: http://krisjordan.com/dynamic-properties-in-php-with-stdclass

Edit:

Try using an accessor:

echo($row->getId());
